luck with Roundup on Asiatic Jasmine.

From the Scotts Co website:

"Some Roundup products are specially formulated with additional active
ingredients to prevent weeds, kill tough brush, or TO PROVIDE FAST VISIBLE
RESULTS." (emphasis mine.)

The non-name brand formulas actually work better as they don't kill off the
top of the plant before the glyphosate works its way through the plant. New
"fast acting" Roundup is useless against wild currants - only the "old"
formula works.
